APPARATUS FOR MEASURING- AND DRAWING OFF LIQUTDSJ" Application filled October 1?, 1922. Serial No. 595,188.

ratus for measuring and drawing of liquid, especially such liquids which are dangerous on account of being more or less hi hly inflammable.

ontr to the apparatus known heretofore in w ch the liquid is introduced into the measuring tank by valves which for divers reasons will not allow a correct measuring or dosing, owin to leakages, and which get easily out of or er, and also contra to such apparatus in which the volume of t e measuring tank can be adjusted by a movable partit1on wall or a piston or the like, and which therefore can easily be tampered with or altered without dificulty in dishonest intentions.

According to the present invention the measuring or drawin 'ofi apparatus is so constructed that the liquid to be measured runs into the measuring tank in a free stream or jet, the measuring tank being provided with an overflow which determines the amount of the liquid to be measured. In connection with this apparatus a device is used, which is operated by the stream of liquid passing the overflow for indicating, when the prescribed amount of liquid is filled .into the tank. The new apparatus forms a closed unit, which does not allow an tampering from outside.

Fig. 1 of the drawing the apparatus is shown in an elevation partly in section.

Fig. 2 is a detail of a modification in section and I Fig. 3 in elevation.

The apparatus consists principally of a measuring tank 1, which by way of example is s own in the drawing as having the shape of a cylinder, having at its lower end an .outletpipe 2, and at its upper end an open neck 3. The latter is surrounded by.

a collar 4 dished to form a cup, from which the pipe 5 branches ofi and which is closed on top by a cover 7. The neck 3 forms an overflow for the measuring tank 1, which is so gauged, that the prescribed volume is obtained, when the liquid begins to run over the neck 3. The; inlet pipe 8 for the measuring tank ispassed throuigh the cover 7 of the cup 4 in such' a position, that the mouth of-the pipe-is situated approximately centrall over the neckB -foi a short distance, so t at the liquid runningout through the inlet-pipe, enters-the tank by the neck in a free stream or jet; "The liquid is drawn out of the reservoir "-9- and fed into the tank b any suitable means fon instance by a pump 10 which may he operated for instance by a handle 20. It is not an absolute necessity that the overflow and the feed of the liquid are dependent from one another. The inlet ipe 8 and the out? let pipe 2,18 are control ed eachby a valve 11. The two valves are lying one'behind the other and may be connected by a; common pivot 19. The two valvesj11= are sov attached to the pivot 19, that, when,-'---'as is shown in the drawing, the inlet-.pipe'=-8:- is open, the outlet pi e 2, .18 is closedand vice versa. There ore no. liquidvcan *be led into the tank as long as the outlet ;.2

18 is not closed.

Means are provided for indicating, when the measuring tank is filled. These means consist of a casing arranged within the overflow pipe 5 and its prolongation 16.

Within the casing 12 a lever 13 is loosely-"- journaled, having at one end a small goblet 14, and on the other end a counter wei lit 15, in itsnormal position is held :be ow the mouth of the pipe 5, reaching intoithe casin whicE has passed the overflow 3, thus will run into the goblet, which when fillediover- 12. The surplus amount of liquid-,

balances the counter wei ht 15, and the lever 13 will oscillate. e last described device can be connected with a signalxof any known description, for instance 'as shown an optical signal, consisting. of=an opening 17 in the wall of the casing '12, opposite to the weight 15, in the sition o the lever 13, which it attains w en fi -2;;

filled goblet overcomes the weight 15.. Thus,

when the weight 15 appears behind the opening 17, it will be understood, that the measuring tank 1 is filled, at which fmoment the pump is to cease operating, and

the valves 11 may be turned to close the inlet pipe and toopen the outlet p1p'e2, 18 to allow the measured liquid to run-out.

When the lever oscillates partxofthe liquid of the goblet .14 will runpvernto" edge and back into the reservoir 9 by the 31fit 'is taken for pipe 16. The small opening 21,,Fig. 2, in the goblet ld will allow the rest of the liquid to'run out, so that the lever 13 thereupon can return to its normal position.

It may be remarked that-the accurate gauging of the measuring tank can be done by grinding the'top edgeof the neck 3.

It may be remarked that the valves. 11 may be situated independently from one another, .inwhich-case the pivot 19 connecting thetw'oivalvesmayfbe omitted.

1n the construction shown in Figs. 2 and .antedtha't the valve bodies are liked to' t e pivot 19 which passes through a'dome '22 attached to the top of thejcasi n 12; Within this dome 22 a lockmem e'r23 preferably in the shape of a se ment,.havin at one end a notch 24 and at t e other 'e'n atoothor stop 25, is keyed to'the pivot 19. A spring-pressed pawl 26' is adapted to catch into the groove 24,.thus locking the se 'ment 23 and by. theaid of the pivot 19 a so the two valves 11; -This pawlis pivoted on a rod 27 opp'OSite the leverj13, provided with a cam 18 which is adapted toengage the pawl 26 i lockingwhen the go1%let ..14 is. in. the position shown full lines in Fi 2. This position of the partswill'takep the during the filling of thefjmeasuring tank 1, thatis to say when thefiinletgvalve 11 is. open and the outlet valve 11 'i'sclosed. ..,When the goblet 14 is filled'an'd moves into the position shown in dottedlines in Fig. 2, the cam 28 is removed from 'the 'pawl 26, thus releasing the locking Inember'23, and now the operator can shut the inlet valve and open the outlet valve. Thus means are provided to prevent the 'measur' tank tobe emptied be fore'it is complete y filled.
